In modern commercial architecture across Windhoek, expansive glass facades create bright, light-filled spaces with panoramic capital views. However, under the intense Namibian sun, large windows present a major building management challenge: balancing natural daylight against heat accumulation and severe screen glare.
Choosing standard interior window coverings has historically meant settling for a frustrating trade-off. Today, available locally at Color Blinds, advanced textile engineering is introducing high-performance window fabrics designed to solve both heat and glare issues simultaneously.
The Core Dilemma: Heat vs. Glare
Evaluating performance fabrics for commercial applications comes down to two universal metrics:
● Rs (Solar Reflectance) — Heat Control: The percentage of solar heat energy reflected away from the window. Higher numbers mean cooler interiors and significantly reduced air conditioning demands in Windhoek's warm climate.
○ Good Benchmark: 40% – 64%
○ Excellent Benchmark: 65% – 75%
● Tv (Visual Transmittance) — Glare Control: The percentage of visible light passing through the fabric into the workspace. Lower numbers mean better glare reduction and increased computer screen comfort.
○ Good Benchmark: 8% – 10%
○ Excellent Benchmark: 3% – 7%
The Traditional Color Trade-Off
Standard commodity screen fabrics force specifiers to pick their poison:
● Lighter Colors: Offer strong solar reflectance (high Rs) to keep rooms cool, but allow blinding light through (high Tv), creating severe glare on office monitors.
● Darker Colors: Excellent at blocking visual glare (low Tv) and maintaining clear views out, but absorb solar energy (low Rs), radiating heat directly into the interior.

The Solution: Next-Gen Commercial Fabrics at Color Blinds
To eliminate this compromise, Color Blinds brings Blind Designs™ high-performance commercial fabrics to Windhoek, engineered with specialized backings and core treatments.
1. Dual-Sided Weaves (Perspective White Back & SheerWeave 4901)
These fabrics use a twill weave with two distinct faces. The side facing inward is dark to absorb ambient light, eliminate glare, and provide visual clarity to the outside world. The exterior-facing backing is white, reflecting solar heat back outside before it can warm up your Windhoek property.
● Perspective 3% White Back (Grey): Delivers an Rs of 52% and a Tv of 8%.
● SheerWeave 4901 (Wheat): Reaches an Rs of 75% alongside a Tv of 6%.
2. Metallised Solar Shields (Perspective 3% Aluview)
Perspective Aluview bonds a microscopic layer of aluminium to the exterior side of a 3% screen fabric. Available at Color Blinds, this metallised backing acts as a high-tech thermal barrier, driving solar reflectance up into the excellent range regardless of interior color selection.
● Aluview White: Delivers an Rs of 73% and Tv of 10%.
● Aluview Black: Combines exceptional glare blockage (Tv of 3%) with strong heat reflection (Rs of 44%).
3. Light-Absorbing White Screens (Perspective 3% Pureview)
Architects often prefer crisp white screen blinds to complement modern Windhoek interiors, but standard white screens suffer from glare. Perspective Pureview incorporates a specialized glare-reducing core. It maintains a bright, clean white aesthetic while reducing Visual Transmittance down to 8% (compared to standard white screens at 15%–21%).
